How to Know When Your Power Steering Pump Is Bad?

Whether you operate a tractor with a John Deere power steering pump or an excavator or loader with a Cummins power steering pump, the performance of your power steering system is critical to the operation of your heavy equipment. When your power steering pump, rack, or pinion has a problem, steering your equipment becomes difficult. This is when it is important to understand the symptoms of the problem and take action. In this article, MyMROmarts will discuss how to recognize the signs of a malfunctioning power steering pump, the signs that you need to replace your power steering rack, and ways to identify a damaged rack and pinion.

 

How to Know When Your Power Steering Pump Is Bad?

Whether it is a John Deere power steering pump or a Cummins power steering pump, the core components of these systems face similar failure risks. The power steering pump is the core component of the entire steering system. It is responsible for providing hydraulic power to the steering rack. When the power steering pump fails, you will notice the following symptoms:

 

1. Steering becomes heavier or loses power

When the power steering pump cannot provide enough hydraulic pressure, steering heavy equipment becomes very difficult. This is especially noticeable at low speeds.

 

2. Abnormal noise

When you hear a harsh squealing sound when turning the steering wheel, it is caused by wear inside the pump or a loose belt. A clicking sound indicates that the internal components of the pump may have been damaged.

 

3. Hydraulic fluid leak or low oil level

Pay attention to checking whether there is fluid leakage or low fluid level in the power steering tank. Insufficient fluid can also cause the pump to overheat or dry grind, exacerbating the occurrence of failures.

 

4. The steering wheel is unstable

Shaking in the steering wheel when you turn a corner means the power steering pump is unable to maintain consistent pressure.

 

What Are Signs You Need Your Power Steering Rack Replaced?

The power steering rack is the component that converts steering wheel operation into vehicle steering. The following signs indicate that your rack is time to replace:

1. Hydraulic fluid leaks

Aging seals on the rack can cause hydraulic fluid leaks. Check the bottom of the heavy equipment for oil stains.

 

2. Steering jams

If you feel resistance to steering when operating the steering wheel, this is caused by wear or blockage of the internal components of the rack.

 

3. Difficulty in steering wheel return

The steering wheel should return automatically after turning. When your equipment has difficulty or cannot return to the center, it may be a rack problem.

 

4. Abnormal metal friction sound

You hear a metal friction sound when operating the steering. This also indicates that the rack is damaged or lacks lubrication.

 

How Do You Know Your Rack and Pinion Is Bad?

The rack and pinion system directly converts the rotation of the steering wheel into the steering action of the vehicle. Here are ways to judge the fault:

 

1. Loose steering wheel or ineffective operation

When you feel that the steering wheel becomes abnormally loose while driving, or does not respond when turning. This may be a problem with the engagement of the pinion.

 

2. Rack offset or misalignment

When your heavy equipment is driving in a straight line, you find that you need to constantly adjust the direction. This may be a deviation in the positioning of the rack and pinion system.

 

3. Abnormal tire wear

Rack and pinion problems will cause the steering angle of the equipment to be incorrect. Long-term use will cause uneven wear of the tires.

 

4. Insufficient hydraulic system pressure

Check whether the hydraulic system pressure meets the standard. Insufficient pressure will also affect the normal operation of the pinion.

 

The power steering system is critical to the operation of excavators, tractors and loaders. By paying attention to common signs of failure in power steering pumps, racks and pinions, you can take timely action. Regular maintenance and replacement of quality aftermarket parts will help keep your equipment in top condition.
